题目:


Every Object Tells a Story凡事皆有戏
Everyone has a particular object to which they attach a special meaning or story. Every Object Tells A (1) is a participative website that enables people to explore the stories and meanings behind collections of museum objects. (2) to the site can create their own stories and share their own interpretations and objects online.
The project (3) on the art of storytelling and involves four regional museums, in partnership with Channel 4 and Ultralab, a (4) technology research centre at Anglia Polytechnic University. It will be led by the Victoria and Albert Museum. It (5) the personal meanings and histories behind objects to get people to look at them in new ways. It (6) designed to inspire them to create their own stories and share their interpretations and objects of personal significance (7) a growing online community.
Video, audio, text and pictures combine on the site to offer an enticing, accessible (8) into the content. Users can choose to browse the hundreds of objects featured, or they can search for (9) particular theme or person. They can decide on the level of information they want on an object, from (10) stories conveyed through text and pictures, to the richer experience offered by accompanying video and audio. They will (11) encouraged to add their own interpretation or object to the collection, by uploading text, images, video or audio (12) the site or by sending text and images from a mobile phone. In so doing, they will be (13) to the website’s content and illustrating how a single object can convey different meanings to different people.
The (14) stories and wonderful objects will appeal to a broad audience. The project has specific relevance to all key (15) of the National Curriculum in English and literacy. Outreach sessions in regional partner museums will encourage people to (16) involved in the project locally and a video booth will travel around England, visiting shopping centres, libraries, bus (17) and the like, to enable people to capture their object and story in a short video. This will (18) be uploaded onto the site.
In addition to the national and local publicity given to the project, Channel 4 (19) promote the website from a number of its programmes, ensuring a wide appeal and providing an added (20) for people to contribute their content.

弗洛伊德将意识分为潜意识、前意识和意识三层面。他认为,“潜意识”是人的意识中被压抑的部分,“前意识”就像一个门卫,起检查作用。当潜意识想变成意识的时候,前意识就会以文明为尺度,检查它是否合乎文明的要求,并决定它是否外化为意识。 以下观点错误的是( )。

A.潜意识能通过前意识的检查

B.意识是潜意识的外化

C.意识合乎文明的要求

D.文明是一种意识

请根据下文回答41-45题:
说到生物世界里的发光现象,人们首先会想到萤火虫,但是除了这种昆虫外,还有许多生物也能发光,人们发现,不同的生物会发出不同颜色的光来,所有的植物在阳光照射后都会发出一种很暗淡的红光,微生物一般都会发出淡淡的蓝光或浅绿光,某些昆虫会发出黄光。仔细地划分一下,生物发光可分两类:一类是被动发光,如植物,那些微弱的红光不过是没能参与光合作用的多余的光,这种光对植物是否有着生物学上的意义目前还是个谜,但一般的看法是这种光无意义,就像涂有荧光物质的材料经强光照射后再置于黑暗中发光那样;另一类是主动发光,尽管有一些主动发光的意义目前还未全部认识清楚,但有一点是可以肯定的,绝大多数生物的主动发光是有用途的。光是一种能量,主动发光是对能量的一种[ ]生物的生存策略有一个最基本的共同点,那就是在维持生命的正常活动中最大限度地去节省能量,因此主动发光必定是主动受光生物生存的一个重要手段。
1885年,杜堡伊斯在实验室里提取出萤火虫的荧光素和荧光素酶,指出萤火虫的发光是一种化学反应,后来,科学家们又得到了荧光素酶的基因。经过科学家们的研究,萤火虫的发光原理被完全弄清楚了。我们知道,化学发光的物质有两种能态,即基态和激发态,前者能级低而后者能级很高。一般地说,在激发态时分子有很高并且不稳定的能量,它们很容易释放能量重新回到基态,当能量以光子形式释放时,我们就看到了生物发光,如果我们企图使一个物体发光,我们只需要它足够的能量使它从基态变成激发态就行了。但生物要发光则需要体内的酶来参与,酶是一种催化剂,并且是高效率的催化剂。它可以促使化学反应的发生,给发光物质提供能量,且能保证以较少的能量使发光强度尽可能高。在萤火虫体内,ATP(三磷酸腺苷)水解产生能量提供给荧光素而发生氧化反应,每分解一个ATP氧化一个荧光素就会有一个光子产生,从而发出光来。目前已知,绝大多数的生物发光机制是这种模式。不过在发光的腔肠动物那里,荧光素则换成了光蛋白,如常见发光水母的绿荧光蛋白,这些绿荧光蛋白与钙或铁离子结合发生反应从而发出光来。

根据文意,下列对“生物发光”的理解,正确的一项是( )。

A.生物发光可以分为两类:一类是无意义的被动发光,一类是具有意义的主动发光

B.生物发光指的是生物在激发状态时因能量释放而形成的一种发光现象

C.生物发光是一种化学发光现象,它只有在两种能态同时出现的情况下才能产生

D.生物发光在发光的腔肠动物那里也需要通过发生化学反应来提供能量
